Great product but overpriced,
Verified Purchase(What is this?)
This review is from: PROMiXX: The Original Vortex Mixer. World's most advanced protein shaker (Misc.)
This is a good product. Basically you add your fluid, and powder at the top. You then press the button and it mixes it up. It's battery powered (2 X Aa). It doesn't come with the batteries, so make sure you've got some handy. On the plus side, it mixes well. My drink was completely mixed up. It's a great product to transport around.
On the downside, I think its pretty expensive for what basically is a blender. Also, it would be handy to put measurements printed on the actual container, as you have to measure your fluid out. Before putting it in here.
Overall, a great product but overpriced.
